Special Issue Information

Dear Colleagues,

The hydrogen evolution reaction (HER) is the heart of various energy storage and conversation systems in the future of renewable energy. Developing a sustainable technology to produce hydrogen efficiently is crucial to realizing the "hydrogen economy", which may address the growing energy crisis and environmental pollution nowadays. Electrocatalytic and photocatalytic hydrogen evolution reactions have received significant attention during the past few decades since they can directly realize hydrogen production from the water-splitting reaction.

Therefore, this Special Issue focuses on recent advances towards the HER, and we invite investigators to contribute original research articles as well as review articles related (but not limited) to the following potential topics:

  • electrochemical (EC) hydrogen evolution
  • photocatalytic (PC) hydrogen evolution
  • photoelectrochemical (PEC) hydrogen evolution
  • water/seawater-splitting hydrogen evolution

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

In response to the challenges of food spoilage and water pollution caused by pathogenic microorganisms, CeO2/g-C3N4 nanocomposites were synthesized via one-step calcination using thiourea and urea as precursors. Steady-state photoluminescence (PL) spectroscopy analysis demonstrated that 8 wt% CeO2/g-C3N4 exhibited superior electron–hole separation efficiency. Quantitative antimicrobial assays demonstrated that the nanocomposites displayed enhanced bactericidal activity against Escherichia coli, Ralstonia solanacearum, and Staphylococcus aureus. Electron paramagnetic resonance (EPR) spectroscopy analysis verified the generation of hydroxyl radicals (·OH) and superoxide radicals (·O2) during the photo-Fenton process utilizing CeO2/g-C3N4 nanocomposites. Additionally, 8 wt% CeO2/g-C3N4 nanocomposites demonstrated enhanced photocatalytic degradation of rhodamine B (RhB) and tetracycline hydrochloride (TC) under photo-Fenton conditions. Full article
